Shit you've done a mistake man.

It will take much longer if you will make 10 selections at a time because windows have a "fake" multitasking.
This mean that it will make you think that all copy-paste work is done simultaneously but it is not. Windows will swich from 1 selection to another until all will be finished. So the inscriptor of your hard-drive will move from one place to another to write your selections. (mechanical moves -->> more time).
To make the time shorter you will have to copy-paste each selection one by one or select all and let it finish the job.
You can get the conclusion that you choosed the worse sollution.
Live and learn
